Recoveries and controls   Leave a comment

I’m always posting updates about our ringing activities on this blog but haven’t as yet posted much about what we have learned from those birds. Of course a lot of the information which we  send to the British Trust for Ornithology concerns biometrics. age categories and dates of occurrence but from our point  of view the most eagerly awaited aspect of ringing is receiving information on recoveries (ringed birds found, living or dead, by the public) and controls (ringed birds re-trapped by other ringers).

Here I present a series of recoveries and controls of birds we have trapped in Dorset over the last couple of years. This is by no means a complete list, but does cover the majority that involve recoveries/controls outside of Dorset. Among the many other within county notifications we have received are;

Sparrowhawk ringed at Durlston, found dead a year later in Christchurch, a Barn Owl ringed as a nestling in north Dorset was controlled near Wareham, a Snipe ringed near Wareham was shot nearby 27 days later, a Woodpigeon ringed in Upton was shot at Lytchett Minster 18 months later, a Herring Gull movement from Weymouth to Brownsea Island was recorded, a nestling Great Black-backed Gull ringed in Weymouth and found long dead on Brownsea Island, a Coal Tit ringed at Lytchett Matravers was killed by a cat in Broadstone a few weeks later.

All the movements below have to be interpreted in context of the birds known migration patterns, for example the Blackcap below probably migrated south to the Mediterranean or north Africa before heading north in the spring to Norway.

Kingfisher

A first year bird that we ringed at Lytchett Bay in August 2012 was retrapped at Fleets Lane in October 2013. As Kingfishers do not breed around Poole this must be a returning wintering/migrant bird. Unlike the other species this photo is of the actual bird concerned.
